"In heaven's name, jump!" For one momentous second Graham could not speak.

He was glad afterwards that darkness hid his face.

He said nothing.

He began to tremble violently.

He looked sideways at the swift shadow that swallowed up the sky as it rushed upon him.
"Jump! Jump--in God's name! Or they will have us," cried Graham's guide, and in the violence of his passion thrust him forward.
Graham tottered convulsively, gave a sobbing cry, a cry in spite of himself, and then, as the flying machine swept over them, fell forward into the pit of that darkness, seated on the cross wood and holding the ropes with the clutch of death.
